Clippr Flutter SDK

Deep linking and mobile attribution SDK for Flutter. A seamless replacement for Firebase Dynamic Links.

Installation

Add to your pubspec.yaml:

dependencies:
  clippr: ^0.0.4

Quick Start

1. Initialize the SDK

import 'package:clippr/clippr.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  await Clippr.initialize(apiKey: 'your_api_key_here');
  
  runApp(MyApp());
}

2. Handle Deep Links

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
    _initDeepLinks();
  }

  Future<void> _initDeepLinks() async {
    // Get the link that opened the app (direct or deferred)
    final link = await Clippr.getInitialLink();
    if (link != null) {
      _handleDeepLink(link);
    }

    // Listen for links while app is running
    Clippr.onLink = (link) {
      _handleDeepLink(link);
    };
  }

  void _handleDeepLink(ClipprLink link) {
    print('Path: ${link.path}');
    print('Campaign: ${link.attribution?.campaign}');
    
    // Navigate based on path
    if (link.path.startsWith('/product/')) {
      final productId = link.path.split('/').last;
      Navigator.pushNamed(context, '/product', arguments: productId);
    }
  }
}

3. Track Events (Optional)

// Track a simple event
await Clippr.track('signup_completed');

// Track with parameters
await Clippr.track('add_to_cart', params: {
  'product_id': '12345',
  'price': 29.99,
});

// Track revenue
await Clippr.trackRevenue(
  'purchase',
  revenue: 99.99,
  currency: 'USD',
  params: {'product_id': '12345'},
);
